The Nissan Skyline R34 GT-R V-Spec is a performance-modified version of the standard R34 GT-R all-wheel drive coupe powered by a turbocharged inline six-cylinder engine producing a factory-rated 280 horsepower. The V-Spec edition features more aerodynamic exterior features than the standard GT-R; it also has a limited slip rear differential and a stiffer suspension with lower ground clearance to further improve cornering performance over stock models.
The R34 generation of Skylines was produced from 1999 to 2002 for the Japanese domestic market and retained the ATTESA-ETS all-wheel drive system and twin-turbocharged engine setup of the previous R33 generation. Like the R33 before it, the R34 Skyline's engine was rated by Nissan at 280 horsepower and 293 foot-pounds of torque, but the Japanese auto industry's unofficial ban on cars with more horsepower led many to believe the actual output of the engine was much higher than the official figures.
Though the V-Spec R34 did not have any upgrades to the engine, the addition of a rear differential to the ATTESA-ETS system allowed the car to vector torque to the rear tires individually during cornering instead of only changing the front-rear torque split as in the standard GT-R. The V-Spec also featured additional gauges for monitoring the engine's intake and exhaust temperatures that were not present on standard GT-R vehicles.
